l C1. i---is'z l 6 Claims. l

This invention relates 'to sink frames and means for mounting sinks in connection therefwith.

The principal object of the invention is the provision of a sink frame and means for mou'ti' ing a sink in engagement therewith.

A further object of the invention is the provision of a sink mounting whereby -a sink bowl may be mounted in a cabinet ope'ning'f.V o

A still further object of the invention fis the provision of a sink frame and mounting for sealing the sink with respect to the supporting structure thereof.-

A still further object of the invention is the provision of a simple and inexpensive -sink frame and mounting which may be easily installed and which is adaptable to various thicknesses of Ysup-'- porting structures as well as various types of sinks.

The sink frame and mounting comprises improvement in the art of mounting sinks and more particularly sink bowls, counter and sink tops such as are customary in the art and where-- in a water-tight seal is desired between the vsurface material of the supporting vstructure and the sink or sink bowl and whereby the' sink bowl may bs held in the supporting structure by the mount-- ing means.v The device disclosed herein comprises a sink frame which overlies the edge of the supe porting structure as well as the edge of the isink or sink bowl and has means suspended therefrom for engaging both the supporting structure. and' the sink so -a-s to hold the `sink in 'desired posi tion in relation to the supporting structure and the sink frame.

The device is therefore readily adaptable for use with various kinds and sizes of sinks and sink bowls positioned in openings formed in various supporting structures whether the 'same are of varying thicknesses of wood and including linoleum or tile tops or metal and either directly finished or provided with an auxiliary wearing surface. Most importantly, the sink frame and mounting disclosed -herein provides a water-tight seal between the sink and a supporting structure and continually maintains the seal in compres-- sion so that the seal remains permanent throughout the life of the installation.

With the foregoing and other objects in view which will appear as the description proceeds. the invention resides in the combination andarrangement of parts and in the details yof construction hereinafter described and claimed, it being understood that changes inthe precise embodiinent of the invention herein disclosed can. be made Within the Scope of what is 'lalid without departing -fr' m the spirit of the yinvolttion.

The invention is illustratedin the accompany--v ing drawing, wherein:

Figure 1 is a perspective View of a portion of a sink supporting structure and sink bowl installed therein.

Figure 2 is an enlarged horizontal section taken on line 2--2 of Figure 1.

Figure 3 is a perspective View of a portion of the sink frame and mounting `shown in Figure 2.

By referring to the drawings'and Figures 1 and 2 in particular it will be seen that a sink supporting structure including a top member I0 and a back wall member II are illustrated and provided with a surfacing material I2 such as linoleum and that the sink supporting kstructure and specincally the top I0 thereof has an opening YI3 formed therein in which a flanged sink bowl I4 is located, the ange thereof being indicated by the numeral I5.

f It will be observed that the opening I3 is larger than the over-all dimension of the flanged sink bowl le. A sink frame I6 of general rectangular shape is positioned partially within the opening I3 in the top I0 and partially overlying the surfacing material !2 thereon. The sink frame VI6 has a transversely convex contour in cross section extending from the outermost edge thereof which is bluntly pointed as at I8. The sink frame I6 also has a depending ange I9 formed thereon which is adapted to be positioned in the opening I3 and abutting the top I0 of the sink supporting structure as best shown in Figure 2 of the drawings. The sink frame I6 has a dovetailed channel 20 formed continuously therein in which the head of a bolt 2l is positioned, the head of the bolt 2l being of the same shape as the dovetailed channel 20 and slightly smaller so that it maybe moved into desired position in the frame I6 by sliding the same along the channel 20v.

The majority of the bolt 2| is provided with a thread pattern 22 and a' wing nut 23 is threadably engaged thereon. Prior to assembling the wing. nut 23 to the bolt y22, a strap clamp 24 is engaged upon the bolt'2`2 by ineans of aoslot 25 formed therein longitudinally thereof,` as best shown in Figures 2 and l3 of the drawings. The strap clamp 24 is of modified arcuate shape, one end thereof forming -a straight extension 26, the outermost Vend 2'I of which is rounded as is the opposite end 28 of the arcuate strap clamp 24. The sink frameand mounting and particularly the strap clamp 24 provides means vfor both liolding the'sink frame I6 downwardly so 'that the ange Il thereof tightly engages the surfacing material I2 on the top I0 of the sink supporting structure and supports the sink bowl I4 by engaging the flange I5 thereon, as shown in Figure 2 of the drawings.

It will be observed that due to the formation and arrangement of the mounting means, includ ing the frame I6, the bolt 2I and the strap 24, the device is operative for its intended purpose regardless of the thickness of the top I0, the surfacing material I2, or both of them, and regardless of the thickness of the flange I5 of the sink bowl I4 as the strap clamp 24 will automatioally assume the proper clamping position with respect to its bearing surfaces on the lower side of the top I0 and the flange I5 when the wing nut 23 is tightened thereagainst. It will be observed that the tightening of the nut 23 both positions the stra'p clamp 24 and holds the sink frame I6 downwardly. Thus the sink bowl I4 is both held in elevated relation in the opening I3 by the device and in engagement with the sink frame I6 which in turn is urged downwardly against the iiange I5 of the sink bowl I4 by the same clamping action.

y It will occur to those skilled in the art that the sink frame I6 may be advantageously formed as an extruded metal product which may be factory formed in accordance with the prevailing practice into the various sizes of frames to match the various sizes of flanged sink bowls so that the same construction is capable of use with any and all sizes of sink bowls in any and all types of supporting structures and regardless of the material or thicknesses of material thereof. In practice, the sink frame IS is installed with waterproof cement beneath the flange Il and beneath the frame IB where it engages the surfacing material I2 and the flange I5, respectively, so that a water-tight seal under continual compression of the clamping device is realized.

It will thus be seen that the several objects of the invention are met by the sink frame and mounting disclosed herein.

Iaving thus described my invention, what I claim is:
